This invention relates to automatic phonofgraphs and more particularly to a novel phonograph apparatus adapted for automatic operation in response to movement of a certain part or structure.

The principal object of the invention is to provide a novel phonograph apparatus in which the actuation of the parts between the playing of successive records is eifected automatically by the movement of a movable structure.

Another object of the invention is to provide a novel phonograph apparatus comprising a stationary structure, preferably in the form of an enclosure for housing the operating parts, a movable structure, preferably of drawer-like form, movable into and out of the enclosure and adapted to support the phonograph turntable, thus permitting access to the turntable whenever the drawer structure is moved outwardly, and means for effecting automatic operation of the phonograph mechanism in response to movement of :the drawer structure to change records.

More specifically, an object of the invention is "to provide novel means, in an apparatus of this ,.chaiacter, for effecting the necessary relative Amovements between the reproducing device and the turntable, and the starting and stopping of the turntable, in response to movement of the answer structure, so that the operator is required to do nothing more than move the drawer structure and place each record on the turntable and remove the record therefrom.

A further object of the invention is to provide novel means for adjusting the apparatus for the playing of different sized records.

A still further object of the invention is to provide a phonograph apparatus in which the tone arm is concealed and is not readily accessible and therefore is not subject to possible damage, especially by children.

Other objects and features of the invention -will appear hereinafter.

Referring particularly to Figs. l and 2, the apparatus shown comprises an enclosure or housing I and an associated drawer structure 2, which together serve to support the operating parts. A tone arm 3 is supported by a bracket li which is xedly secured to a part of the housing i. A reproducer or pick-up device of any known form may be provided on the tone arm. A turntable 5 (Fig. 6) is rotatably mounted upon the drawer structure 2 so that it is movable outwardly to an accessible position, as shown in Fig. 1, to permit the placement of a record on, and removal thereof from, the turntable. In the illustration a record 6 is shown on the turntable. As described hereinafter, the movement of the drawer structure effects the necessary relative movements between the pick-up device and the turntable between the playing of successive records, and also controls the rotation of the turntable.

The tone arm 3 is suitably mounted on a supporting post 1, as shown in Fig. 6, for vertical and horizontal movements with respect to a record on a turntable, as will be well understood. The supporting bracket 4, which carries the post l, maybe secured to a wall of the housing. The tone arm is actuated by a rod 8 which is slidable and rotatable within the hollow post structure which the rod 3 extends, Thus, the slot-like and which is actuated irl IeSDOnse to movement opening I8 permits the drawer assembly to be 0f the drawer Structure 2, 21S Will be described moved outwardly or inwardly with respect to the in detail hereinafter- At its upper end the rod housing and the tone arm structure, including 8 has a laterally-extending arm 9 (Fig. 4) which 5 the lift rod 3,

Since the playing of the record is now finished, the user or operator moves the drawer structure outwardly to the position shown in Fig. l. During the initial outward movement of the drawer structure, the lower end of the tone arm lift rod 8 engages the inclined surface 23 (Fig. 4) and rides upward therealong to the upper floor level 2li-of the cam structure 2 l. This causes the tone arm to be elevated, moving the stylus out of engagement with the record. Shortly afterward, the switch I2 (Fig. 2) is permitted to open in the manner above described, thus deenergizing the driving motor for the turntable and causing the turntable to come to a stop.

In the meantime the outward movement of the drawer structure brings the Wall portion tl (Fig. 7) of cam rail 26 into engagement with pin 213, and as the pin rides along the surface 4I the tone arm is swung outwardly with respect to the record. Continued movement of the drawer structure causes the pin to move along the wall surface 42 of cam rail 26, and-when the drawer structure nears the limit of its outer movement, the pin 2li engages the movable cam member 3@ and deects the latter suiciently to permit the pin to enter the track 43 defined by the adjacent cam members. The drawer structure is now in its outermost position, and the operator removes the played record and places another record upon the turntable, and then moves the drawer structure inwardly.

During the inward movement of the drawer structure, the pin 20 is guided by the surface :it (Fig. '7) of cam member 3l! into the narrow passage or track between rails 21 and E3. Subsequently the pin 20 enters the space between rail 21 and the movable cam member 2S and deflects the latter suiciently to permit the pin to move to the position shown in Fig. 3. At this time, the tone arm is properly indexed for placement upon the marginal portion of the record.

In the meantime the inward movement of the drawer structure will have caused the switch l2 to be closed by the cam member I3, thus initiating rotation of the turntable and the supported record. During the latter *portion of the inward movement of the drawer structure, the lower end of lift rod 8 rides downward along the inclined surface 23 (Fig. 4), thereby lowering `the tone arm and bringing the stylus into engagement with the record. By the time this occurs, theturntable will have been brought up to speed and the tone arm will have been properly indexed, as shown in Fig. 3. The operating cycle is now completed and the playing of the record commences.

From the foregoing description, it will be seen that the apparatus of Figs. 1 Ato 8 operates automatically in response to movement of the drawer structure by the operator. It will be apparent of course that the movement of the tone arm, in response to manual movement of the drawer structure, is the most important feature of the above described apparatus. While it is preferable that the apparatus shall embody suitable means for controlling the operation of the turntable in response to movement of the drawer structure, it will be apparent that this functioncould be per formed by means of a manual switch instead. However, this would require operation of such a switch in addition to the manual movement of the drawer structure.

The operation of the apparatus during the playing of ten inch records is'the sameas'above described, the only :difference :.bein-gfthat the cam structure 2l is differently positioned to index the tone arm properly When the adjusting mechanism is set for the playing of ten inch records the indexing portion of cam member 2l will be positioned as shown in dot and dash outline at A in Fig. 3. Consequently the stylus end of the tone arm will be properly indexed with respect to the smaller sized record, as also shown in dot and dash outline in Fig. 3.

While the specic form of the cam structure 2l is preferred because it assures proper cycling of the tone arm even if the apparatus is jarred or tilted during the cycling operation, it is not necessary to employ this specific structure. That is to say, any structure having a suitable cam track may be employed.

In Figs. 9 to 11, there is shown a modification in which the cam structure and the adjusting mechanism take different forms than those of the above described embodiment. Referring to Fig.

9, a portion of the stationary housing is shown at 4G, while the drawer structure is designated generally by reference character 41. In this instance, a cam gear t8 is rotatably mounted on a spindle 439 carried by a bracket 50 which is secured to the housing 4E. The drawer structure is provided with an elongated slot opening 5i' to accommodate the spindle 49, and there is provided on the drawer structure a gear rack 52 which meshes with the cam gear as shown. The parts are shown in the positions which they a.,- sume when the drawer structure is in its innermost position, and as the drawer structure is moved outwardly the rack 52 moves in the direc-- tion indicated -causing the cam gear t8 to rotate clockwise as viewed in Fig. 9, as indicated by the arcuate arrow.

The tone arm mounting is similar to that previously described and comprises a hollow post 53 supported on a bracket 54. The tone arm actuating rod 55 is also similar to that of the previously described embodiment but, in this instance, the lower end of the rod engages the peripheral portion of the cam gear fit, which has a depression at 56 for lowering the tone arm onto the record. An arm 51, carried by rod 55, has a depending pin 58, which is actuated by the cam gear in a manner which will be presently described.

In order to adapt the apparatus for the playing of different sized records, the cam gear i8 is provided with selectable tracks 59 and B, in which the pin 58 is adapted to ride. A pivotal selector member Ei! is arranged as shown and is normally spring-biased into the position shown in Fig. 9. A shoe E2 is carried by the pivot of member 6l below the cam gear and serves to actuate member El when the apparatus is adjusted for the playing of twelve inch records. The adjustment is effected by means of the mechanism now to be described.

Rigidly secured to the housing structure is a bracket E53 carrying a vertical rod Gli. Slidably mounted on rod 312 is an actuator 65 (see Fig. 11) which is adapted to be positioned to engage shoe 62 when adjustment is made for the playing of twelve inch records. An adjusting lever (see Fig. 11) is pivotally mounted on bracket t3 at 6'? and has a cam slot 68 engaging a proies-- tion 59 on the actuator 65, The lever 6&3 extends upward through a slot 'Hl within an escutcheon plate lli mounted in the top of the housing.

In the illustration of Fig. 9, the lever i5@ is shown adjusted .for the Vplaying oftwelve inch records and the parts-are 'shown just after-'the drawer structure has been moved inward4 to initiate operation. At,V this time thepin 58 is disposed as shown in Fig.,9. and the Y,tone arm is' in its lowered position with thestylus engaging the marginal portion ofY the record 12. Owing to the adjustment of lever 5,6 the, actuator 65 is positioned to engage shoe B2 during the cycling operation, as will be. presently shown.

During the playing of the record, the tone arm moves inward vand the pin 58-imovesinward in the cam recess'. When the end of the record is reached, the operator moves the drawer structure outwardly, causing the cam gear to rotate as previously mentioned. This causes the lift rod 55 to rise out of the depression 56, thereby lifting the tone arm from the record. As the cam gear rotates, the pin 58 follows the inner track or recess 13 until it engages a pivoted element 14 which is spring-biased to the position shown. The pin 58 deiiects this element and enters the track 14a. At this time the drawer structure is in its outermost position and rotation of cam gear 48 ceases.

After having changed records, the operator moves the drawer structure inward, causing the cam gear to rotate in the reverse direction. In the meantime, the shoe 62 will have been engaged by the actuator 05, causing member to move inward. Consequently the pin 59 enters the outer track 60 and moves therein until it reaches the position shown in Fig. 9. W'hen the drawer structure has almost reached its innermost position, the pin 58 drops into the depression 56 and lowers the tone arm to bring the stylus into engagement with the marginal portion of the record. This occurs immediately prior to the time that pin 58 reaches the position shown in Fig. 9. The operative cycle has now been completed and a new cycle commences.

When it is desired to play ten inch records, the operator moves lever 66 to the ten inch position. In this position the cam slot 59 permits the actuator 65 to drop to a lower position in which it is ineiective to actuate the shoe S2. Therefore, during the operating cycle, member El remains in the position shown and the pin 58 traverses the inner track 59 instead of the cuter track 60. This indexes the tone arm in proper relation to the smaller record. Otherwise the operating cycle is the same as above described.

It will be understood that the rotation of the turntable in the embodiment just described may be controlled in the same manner as in the mst-described embodiment. That is to say, the turntable driving motor may be controlled by a switch actuated in response to movement of the drawer structure.

In Figs. 12 and 13, there is disclosed a further modication of the invention in which the turntable is moved to eiect engagement and disengagement of the pick-up stylus and a record on the turntable. Referring particularly to Fig. 12, portions of the stationary structure or housing are indicated by reference character 15, while the movable drawer structure is shown at 16. As before, the tone arm 11 is suitably mounted on a supporting post 18 which, in turn, is mounted on a bracket 19 secured to the stationary housing, However, the tone arm actuating mechanism is somewhat diierent than in the previous embodiments, as will be presently described.

In this instance, the turntable 80 is rotatably supported by a suitable bearing structure 8| carried by the drawer structure 16 and the turnbearing 8|.

ydrawer structure 16 is in its innermost position,

the lower end ofl spindle 02 engages the surface of the cam rail 89,fbut when the drawer structure is moved outwardly the spindle 82 is permitted to drop by virtue of the incline 86 and the lower surface 80, thereby causing the turntable to be lowered and disengaging the record 81 from the pick-up stylus.

In this instance also, the driving motor 88 for the turntable is mounted on the stationary housing structure 15 by means of a suitable supporting plate 89. The motor is intended to run continuously during the operation of the apparatus, and the driving of the turntable is eiected by moving the latter into and out of engagement with a driving wheel 90 arranged to engage the peripheral edge portion of the turntable. The wheel 90 is carried by a plate 9| which is movably mounted on the plate 89 by means of pin 92 on the latter and a slot 93 in the plate 9|. A small driving pulley 94 connected to the motor shaft serves to drive the wheel 90. A spring 95 has one end connected to plate 9| and its other end anchored to plate 39, as shown, and serves to urge the driving wheel 90 into engagement with the turntable and the driving pulley 94. When the turntable is moved during outward movement of the drawer structure 16, it is disengaged from the driving wheel 90, thereby interrupting the rotation of the turntable. 'I'he drawer structure is suitably recessed, as shown at 96, to accommodate the turntable driving assembly.

Since the turntable is moved in the manner above described, it is unnecessary to move the tone arm vertically but it is necessary to move it laterally. Therefore, there is provided a suitable mechanism for moving the tone arm laterally in response to movement of the drawer structure. A cam plate 91, having depending side portions 98 and 99, is pivotally mounted at |00 on the drawer structure 16 and is supported at its other end by a shelf |00a. A cam member |0| in the form of a deliecting bal` is pivotally mounted at |02 on the underside of the cam plate 91. The upper surface of plate 91 is recessed at |03 and carries a short pin or Stud |04. A spring finger |05 is secured to the upper end of the pivot pin |02 and engages the stud |04. This spring linger serves to urge the bar |0| into engagement with the sides 98 and 99 of the cam plate 91, as clearly shown in Fig. 12.

The tone arm actuating member is of the same general form as in the preceding embodiments and has an extending arm |06 carrying an upstanding pin |01 which extends into the space between the sides of the cam plate 91. Stop pins |08 are provided on the tone arm supporting bracket 19, and a cooperating extension |09 is provided on arm |95 to limit the lateral movement of the tone arm.

The adjustment of the apparatus for diierent sized records is effected by means of an eccentric disc ||0 disposed within a rectangular opening l at the end of plate 91 opposite its pivotal support. The disc ||0 is carried by a rotatable shaft ||2 supported by the drawer structure 16. A knob I I3 is provided on the shaft l2 for rotating the disc IIB. When the disc Il`0 isv moved between the solid line and dot-and-dash positions of Fig. 12, the cam plate 9'! is adjusted for the diierent sized records.

Considering the operation of the apparatus, when the drawer structure is in its innermost position, the turntable is indrivingv relationship with the driven wheel 90 and is also in position for engagement with the pick-up stylus. Assuming that the apparatus is adjusted for twelve inch records and that the drawer structure has just been moved to its innermost position, the pin 401 will be in the position shown in Fig. l2, thereby properly indexing the stylus with respect to the marginal portion of a record on the turne table. During the playing of the record, the pin itil moves toward side 99 of the cam plate Q'l as the tone arm moves inwardly over the record. When the stylus reaches the end of the sound groove, the pin |01 will be disposed closely adjacent to side 99.

When the playing of the record is completed, the operator moves the drawer structure 'It outwardly and this immediately causes the turntable to drop downward out of engagement with the stylus, owing tothe location of the incline Se on the cam rail' 33. Theturntable is also moved out of engagement with 'the' driving wheel 9S, thereby interrupting the drive and causing the turntable to come to a stop. In the meantime, the movement of the cam plate 9i with the drawer structure causes thepin H31 to vengage and deilect the bar 10| so that the pin is now on the rear side of the said bar.

When the operator moves the drawer 'structure' inwardly, after'having placed a new record on the turntable, the pin 101 is caused to 'ride along the rear side of thebar IUI, which deilects the pin in a manner to cause outward movement of the tone arm'. Finally, the pin lll deflects the bar ll and reaches the position shown in Fig. 12, at which time the'tone arm is" indexed for the ccmmencement ofthe new record. In the mean# time, the turntable is elevated'jb'yth'e cam rail 83, bringing the record into-engagement with the stylus,`and' the turntable isalSoA moved into engagement with the driving wheel Q0. Consequently, theplaying of the new record Icommences and the cycle is repeated.

When it iszdesire'd to us'ethe apparatusin con-l junction with 'ten linch records, the knob H3 is rotated to move the eccentric disc I Ill to the dotand-dash position shown inV Fig. 12. Such adjustment moves the cam plated? so as to change the indexing position of the pin' H01 and thus effect proper indexing 'of the stylus for the playing of ten vinch records.I In operation, theapparatus functionsin'the :samev manner as it does with twelve inch records, as alreadydescribed.

From the foregoing description, it vwill be'seen invention may be employed in conjunction with' a radio receiver or other apparatus,` in which case a common housing may be employed, as in the well-known radio-phonograph combination. Further, the invention is not limited to the particular *embodiments illustrated and described 10 but isy susceptible of "various other modifications and embodiments.
